Fixing the problem with Sidebar-alignment

Currently, when the sidebar is taken from right side of
the screen to left side of the screen, the vertical tab
-bar is still attached towards the right side of deck.
Ideally, when the sidebar is attched towards the left
side of the screen, the tab-bar should automatically set
towards the left side of deck.
